Figure 7-10 8-bin Mailbox Power Supply Test Mode Switch 1 Plug in the power cord. The User LED should be solid green, and the Service LEDs should be ‘Off, Solid Red, Off’ to indicate the test mode has been entered. Note Be sure to reset the power supply switch to the normal operation when you finish the diagnostics; otherwise the unit will not work properly. Power-on Test 1 Push the 8-bin Mailbox interlock switch and keep it pressed. A sequence of tests will begin to test the device. 2 The head assembly will move up and down twice, scanning that all unit bins are properly installed and that all unit motors have started.
3 At the end of the power-on test, the flipper motor remains on and waits for paper to be fed. 4 The User LED remains solid green and the service LEDs remain ‘Off, Solid Red, Off’ as an indication that the power-on test was successful. 5 If a problem exists, an error code will be shown in the Service LEDs. (See table 3-3 for an interpretation of the LEDs.) 454 Chapter 7 Troubleshooting C4085-91087
